The increase of environmental pollutants especially heavy metals derives from human industrial communities. Zinc is one of the natural elements that exist in biotic environment, plants body, and animals in different forms. Zinc has toxic and lethal effects in high concentrations on plants. Also some plants are introduced as accumulators of this element. Therefore, an investigation was carried out to consider different concentrations of Zn on Plantago major in completely random form and with three replications. The ZnSO4.7H2O was included at 0, 50, 100, 250, 500, and 700 µmolar concentrations that were applied to the plants during 8 days. The results indicated that catalase enzyme activity increased significantly in comparison with control in root and shoot except at 50 µmolar concentration. Ascorbate peroxidase enzyme activity increased significantly only at 50 and 500 µmolar concentrations in comparison with control in shoots but it increased significantly in root with increasing metal concentration. Peroxidase enzyme activity increased significantly only at 50 and 700 µmolar concentration in shoot; however, this enzyme increased significantly in root with increasing metal concentration except at 500 µmolar concentration. The amount of proline increased significantly with increasing of zinc concentration. Soluble carbohydrates decreased significantly in comparison with control in root and aerial organs except at 700 µmolar concentration. These results derive from plant resistance against high concentrations of Zn. Manuscript profile

Thymus daenensisis a perennial plant belonging to Lamiaceae family that is a species endemic to Iran. Due to the indiscriminate use of this plant which possesses medicinal values, T. daenensis tissue culture is suggested to increase the quality and quantity of its effective compounds. Callus cultures using leaf and stem explants were subjected to different hormonal treatments. Ten-millimeter explants of leaves and stems were cut up from sterile seedlings. MS medium was used with different concentrations of naphthalene acetic acid, benzyl amino purine, kinetin and 2,4-D (mg per liter) in which callus formation was observed. The highest level of thymol (28/1335 micrograms per gram) was recorded in calluses derived from leaf explants whereas the lowest level was observed in calluses obtained from stem explants. Also the highest levels of thymol, i.e. 65/1313 and 30/1322 micrograms, were observed in treatments of 0.4 NAA+3 BAP and 0.8 NAA+6 BAP mg per liter, respectively. Moreover, the interaction of effects of different treatments of calluses and different concentrations of hormones showed that the highest level of thymol (38/1345 micrograms per gram) was obtained from the treatment of NAA+1.5 BAP 0.2 mg per liter in the calluses derived from leaf explants. In addition, the maximum callus weight (22.1 grams) was related to the treatment of 0.8 NAA+6 BAP milligrams per liter. Results of the callus culture of T. daenensis to enhance the quality and quantity of its active ingredients showed that different explants and hormones with different concentrations and as well as their interactions had a significant effect on the level of thymol and callus weight (p≤0.01).

For considering the effect of drought stress on some morphological and biochemical changes in two pumpkin species, Cucurbita maxima L. and Cucurbita pepo L. a kind of experiment was done by field culture in three water dispersal levels with field capacity, 2/3 field capacity, and 1/3 field capacity, based on the factorial design in random block form with four replications. The results indicated that increasing the stress level, leaves water potential under drought stress decreased in comparison to the control sample in both species. But with increasing drought stress, root length increased too. Also during drought stress, root soluble carbohydrates content, ascorbic acid content, dehydroascorbic acid, catalase, polyphenol oxidase, and peroxidase enzymes activity increased significantly in 5% level, according to the results with increasing the stress, soluble carbohydrates content decreased in leaf.
